In this paper the synthesis of fluoralinite cement and its hydration properties are presented. It was determined, that fluoralinite has been obtained after 4 hrs at 1100 °C temperature without difficulty, by using in the initial composition of 0.89 % Al2O3, 1.78 % MgO and 0.89 % Fe2O3 additions. Specimens, formed from fluoralinite clinker and grinded sand (fluoralinite clinker and sand mass ratio 1:3) and hydrothermal cured at 175 °C for 4 hrs, had the biggest strength (4.68 MPa). Thus, fluoralinite cement is usable for hydrothermal curing articles. X-Ray analysis has shown, that, while hardening of the mix of fluoralinite and quartz sand for 28 days in normal conditions, quartz, tobermorite gel, portlandite Ca(OH)2 and CaF2 prevail in the samples. Whereas this mix hardens in hydrothermal conditions, calcium hydrosilicate C - S - H (I) and Ca(OH)2 form.
